“…For Gh, aer 40 mg, the adsorption capacity did not signically increase, that can be explained by either the lling of nearly all the sites of the surface of our adsorbent or by inter-particle interactions caused by the agglomeration of the clay particles between them, as it was reported in this work. 16 In the case of ca-Gh, the adsorption capacity has almost reached its maximum aer 15 mg, which may be concluded from the nearly complete removal of all the cadmium ions from the solution.…”

“… 20 The effectiveness of Ghassoul in adsorbing malachite green and basic yellow 28 from an aqueous solution is already discussed in the literature. 21 Another study looked at this Moroccan clay's ability to remove cationic dye from aqueous solution. 22 Ghassoul has also proved its potential in removing heavy metals.…”

“…It is an abundant Moroccan stevensite and its use in water treatment applications was the subject of numerous investigations. 16,19 It was mentioned that stevensite can exchange the cations stored in its aluminosilicate structure for cations from an external solution through the process of ion exchange. 20 The effectiveness of Ghassoul in adsorbing malachite green and basic yellow 28 from an aqueous solution is already discussed in the literature.…”

In the present study, the ability of an adsorbent (SLM Stem) obtained from the stem of the Silybum Marianum plant to treat wastewater containing the cationic dyes basic blue 3 (BB3) and basic yellow 28 (BY28) from aqueous solutions was investigated using a batch method. Then, the SLM Stem (SLM Stem-Natural) adsorbent was carbonized at different temperatures (200–900 °C) and the removal capacity of the products obtained for both dyes was examined again. The investigation continued with the product carbonized at 800 °C (SLM Stem-800 °C), the adsorbent with the highest removal capacity. The dyestuff removal studies were continued with the SLM Stem-Natural and SLM Stem-800 °C adsorbents because they had the highest removal values. The surface properties of these two adsorbents were investigated using IR, SEM, and XRD measurements. It was determined that the SLM Stem-Natural has mainly non-porous material, and the SLM Stem-800 °C has a microporous structure. The optimal values for various parameters, including adsorbent amount, initial dye solution concentration, contact time, temperature, pH, and agitation speed, were investigated for BY28 dye and were 0.05 g, 15 mg/L, 30 min, 40 °C, pH 6 and 100 rpm when SLM Stem-Natural adsorbent was used and, 0.15 g, 30 mg/L, 30 min, 40 °C, pH 10, and 150 rpm when SLM Stem-800 °C adsorbent was used. For BB3 dye, optimal parameter values of 0.20 g, 10 mg/L, 30 min, 25 °C, pH 7, and 100 rpm were obtained when SLM Stem-Natural adsorbent was used and 0.15 g, 15 mg/L, 40 min, 40 °C, pH 10, and 100 rpm when SLM Stem-800 °C adsorbent was used. The Langmuir isotherm described the adsorption process best, with a value of r2 = 0.9987. When SLM Stem-800 °C adsorbent was used for BY28 dye at 25 °C, the highest qm value in the Langmuir isotherm was 271.73 mg/g. When the study was repeated with actual water samples under optimum conditions, the highest removal for the BY28 dye was 99.9% in tap water with the SLM Stem-800 °C adsorbent. Furthermore, the reuse study showed the adsorbent’s efficiency even after three repetitions.
